Hi, For ODE we're managing our transactions ourselves. We start them and commit them explicitly. By the same token we create the EntityManagerFactory ourselves. Is there a possibility to use the EntityManager injection in the persistent classes in this context or do we have to implement our own ThreadLocal based thingy to have the EM available in our persistent classes using it?
I've tried doing something like: 1. Adding "@PersistenceContext private EntityManager _em;" in a persistence class. 2. Load the persistence class from an EntityManager created with the factory. 3. Use _em in my persistent class => NullPointerException Thanks, Matthieu
